- Abstract:
The article reports that the World Health Organization has granted emergency use for a new oral polio vaccine for eradicating polio. It mentions that low vaccination rates allowed altered vaccine virus, shed in the stool of the immunized, to spread and, over time, return to a form that causes paralysis. It also mentions the comments of medical epidemiologist Chima Ohuabunwo of Morehouse School of Medicine in Atlanta.
